Utility structure monitoring and hazard detection system
The granted patent US12034294B2 outlines a comprehensive utility structure monitoring system designed to enhance safety around utility power lines. The system incorporates various sensors, including angle switches, laser sensors, photoelectric sensors, cameras, and thermocouples, which are strategically configured to detect potential hazards at predetermined distances from the power lines. Upon detecting a hazard, such as a shift in the utility structure or an object breaking the line of sight, the system generates a hazard signal that triggers a hazard alert. The sensors can also identify temperature anomalies and electrical arcs, ensuring a proactive response to potential dangers.
Additionally, the patent describes a fire box that contains arcs emanating from power lines, further mitigating fire risks. The system is capable of conducting alerts based on multiple hazard types, including structural shifts, line of sight interruptions, and temperature thresholds. The integration of light emitting and receiving elements allows for real-time monitoring of the area surrounding the power lines, enhancing the system's responsiveness. Overall, this utility structure monitoring system aims to improve safety protocols for high-voltage power lines by providing timely alerts and automated hazard responses.
